Welcome to the Q&A Forum

I'm trying to figure out why a site has been stuck at the end of the SERPs for almost a year.  On August 5, 2011 the site went from getting 1,400 visits per day from Google down to 20 visits a day from Google.  For the keywords it ranked on the first page for it went to the last page in the SERPs.  With Panda and Penguin, it probably wouldn't rank like it used to, but it seems to be stuck in some sort of domain wide penalty that pins it to the end of the SERPs.  Even when completely new content  will show up at the end of the SERPs, which makes me think it's stuck in some sort of filter.  Thanks in advance for any constructive ideas.
